I'd prefer it if bulk-collected data that was collected prior to a warrant, by anyone, was inadmissible under 4th Amendment guidelines, and that it could also not be used for investigative purposes.

However, I have a hard time squaring this with the fact that I think it's legit for cell phone records to be gathered, and then used under warrant in the event of a major criminal investigation--including location pings. That is, I'm okay with the police being able to discover Joe Murderer wasn't actually in Las Vegas when his wife got strangled. But if they start using license plate tracking to try and nail Jill Nobody for underpaying some ridiculous road tax, then I start to have a problem. How the heck do we draw that line?

(1) No plea bargaining. If it isn't worth bringing to trial, it's not worth charging. (2) Jury nulliification. If the good citizens think the prosecution was stupid and vicious, even if technically sound, they decline to convict.
